yes, this is an assignment, but i am not asking for any help on it (yet lol)
I was just wondering how hard would this be? when i first saw the requirements i thought it would be really easy
it must:
have a graph with equally sized boxes and labels on x and y axes for the coordinates (easy thats just drawing stuff)
convert all equations that the user types in to y = mx + b form
be able to graph circles, lines, parabollas

should be quite easy... all you do is run a forloop from half the screen size to half the screen size to find the Y value from the equation. Then you add half the screen size to the X to move it in place (so the middle of the screen is 0).
Also, instead of drawing single points, you gotta draw a line from 1 point to the next so that the graph will look like a continues line, not a bunch of scattered dots.
